SPECIFICATION forming part of Letters Patent No. 333,227, dated December 29,1885.

Application filed Oct-her 6, 1883. Renewed June 16, 18 4. Serial No. 135,045. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM H. HUNTER, a citizen of the United States of America, residing at Farnhamville, in the county of Calboom and State of Iowa, have invented certain new and useful Improvements in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of theinvention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain improvements in cultivators; and it consists of theimproved construction, fully described hereinafter, whereby the height of the draft-frame and tongue can be readily adjusted with respect to the beams and shovels, the beams readily aita-hed to the frame at different vertical and lateral adjustments, and the general construction improved and simplified.

In the accompanying drawings, Figure 1 is a side view of a cultivator constructed in accordance with my invention. Fig. 2 is afront view of the same. Fig. 3 is a perspective view of one of the beamsections. Fig. 4 isa detail view of one of the shovels and part of astandard. Fig. 5 is a detail view, and Fig. 6another detail view.

A B represent two vertical standards formed at their lower ends into square frames a b,provided with an elongated opening, a, in the top bar, and a series of perforations, c, in the bottom bar of the same, and stub-axles 0, formed integrally with the side bars of said frame, upon the ends of which axles turn the carrying-wheels D. An arched bar, E, spans the two vertical standards A B, and is provided at its vertical ends with loops d d, which embrace the said standards, connecting the arched bar to said standards, but permitting a vertical adjustment of the former on the latter. Centrally on the top of the arched bar is secured, by bolts or otherwise,the rear end of the drafttongue F, which is braced by rigid diagonal and horizontal braces e e, secured to said tongue, and extending back for a' distance in the rear of the arched bar, and secured thereto where they cross the same.

Inclined rods f, bolted at their lower ends to the lower inner sides of the standards A B, extend nearly to the draft-tongue F, and rods f of a corresponding length, bolted at their upper ends to the said draft-tongue, extend nearly to the lower end of the rodsf, and are retained in connection therewith by a loop, f two rods, and loop connections forming vertically extensible braces for the tongue. A double-tree, G, is pivotally secured to the tongue, and a pivoted neck-yoke, secured to a swivel-pivot, is located at the front end of the tongue.

, Both the vertical portions of the arched bar and the standards A B are provided with a series of perforations, 'h, through which a securing-bolt, h, is adapted to be passed to hold securely the arched bar in any of the vertical positions it. may be adjusted upon the standards A B. The rods ff have also perforations z and a bolt, i, for effecting the secure adjustment of the rodf on the rod f.

Within each frame a b is a vertical bar, H, provided with a series of perforations, j, and rounded at its lower end to bear in one of the perforations in the lower bar of each frame. Each of the said bars H is provided with a rib, is, which, in addition to the main portion k of the body of the bar, can be readily passed into each frame through the elongated opening in the top thereof, and the bar then turnedto bring the rib beneath the bar adjacent to the elongated slot, to prevent the removalof said bar from the frame without turning the same, the lower rounded end of the bar bearing in one of the perforations c in the lower bar of the frame.

Links I, each having a head, Z, at one end, are recessed at the other end to embrace the bars H, and each has transverse perforations m, adapted to register with those in the bar, and be retained in connection with the said bar by means of a bolt passing through the perforations of said link and bar. The head Z of the link I is bolted by a swivel-bolt be tween corresponding heads, J J, of horizontal clamp-plates K K. The upper clamp-plate, K, has a U-shaped groove, a, on its under side, and thelower plate, K, has a corresponding groove, a, which, when the plates are clamped rigidly together, form a U-shaped recess of suffioient size to receive the U-shaped end of a double beam, L L, which is placed IOC therein and the plates bolted together. The rear ends of the beam L L are curved to form vertically-inclined standards M M, each having a shovel, p, formed with astraight upper edge, p,against which a supplemental shovel, p, curved as shown in Fig. 4, can be bolted to act in the capacity of a mold-board for the lower shovel. A wedge-shaped block, q, interposed between the lower end of the standard and the rear faces of the shovel'sections 1212 increases the inclination of the shovelsections, if desired.

Each beam-section has securely bolted between its rear horizontal parts a brace, r, having lugs r r, between which and the sides of the beams L L the ends of the handles N can be inserted, a bolt passing through the beams, handle, and shoulders rigidly securing the several parts together. 7

If desired, an additional standard, 0, a shown in Fig. 2, and its shovel t can be added to either the beam L or L. The said standard O is horizontal at its upper end, 15, and is laterally curved at said end, that its shovel may be equidistant with respect'to the shovels of the beams L L, and is beveled at the side of the said upper end to rest in a groove of a bearing-blocl P, a bolt,t", passing transversely through the end it of the standard, the bearjug-block, and beam to securely fasten all theparts together. A shouldered brace, u, designed to fill the office of the brace r, may be bolted between the standard 0 and the beam.

Clips Q embrace the vertical sides of the arched bar and the standards A B, and are clamped thereto by clamp-plates having perforations through which the threaded ends '0 of the clips pass and retained by nuts w. The neck R of each clip is perforated to receive the end of a horizontal bar, 8, which extends back over the beam-sections, and is provided with a chain, as, for attachment to the beam-sections, to more firmly brace the same with respect to each other and the draft-frame.

Hooked links T are hung in perforated ears on the axle, and can be hooked to suitable chains or straps connecting with the collars of the team, so as to also secure a draft on a line with the axles.

Bythe construction of the cultivator described the draft-frame can be easily lowered or elevated with respect to the beams, and by moving the lower ends of the bars H, so as to rest in the different perforations c of the frames, the beams, and their connections with the bars H, can be readily adjusted to any desired degree of lateral inclination, and that the parts composing the machine are of a construction tending to make the machine as a unit thereof both durable and simple, and that the said parts can be readily and conveniently cast with but little labor.

I claim- 1. In a sulky plow or cultivator, the frames having rigidly attached thereto stub-axles G on one side and vertical standards on. the other, in combination with an arched bar provided nearits ends with loops, said bar sup-'- portingthe tongue, and extensible and adjust able braces, the parts being organized substantially as shown, for the purpose set forth.

2. In a sulky plow or cultivator, the combination of an adjustable arched bar and carrying-frames with axles formed thereon, and
